On hydroponic farming

This week, we’ll hear how some farmers are using hydroponics technology to save on water, and revisit an interview with biologist Edward O. Wilson.

Much of the country has been cracked open by heat and drought this summer, and farmers are feeling the pinch of low crop yields and battles over water rights. What if there were a way to grow crops using, say, 90 percent less water? Enter hydroponics technology. Sounds like magic – but while it’s gaining popularity, it has a long way to go before it can start working agricultural miracles. Hilary Stohs-Krause has more in a report for Harvest Public Media.

And, biologist Edward O. Wilson is an emeritus University Research Professor at Harvard. Through his life-long research on the behavior of ants, he’s transformed the disciplines of ecology and evolutionary biology, developing new theories and pioneering the field of sociobiology. We'll revisit an interview between Wilson and St. Louis Public Radio's Véronique LaCapra
